Eppendorf BioPhotometer

Eppendorf BioPhotometer

State-of-the-art technology with an easy-to-use format in a compact footprint:
that is the Eppendorf BioPhotometer! It's large key pads, pre-programmed
methods, and pre-set wavelengths and conversion factors greatly simplify the
sample quantification. The large LCD screen displays the sample concentrations,
absorption values, OD260/OD230 and OD260/OD230 and sample dilutions at a glance.

• Compact design, easy to transport
• Robust housing, splash- and water-resistant
• High-value components guarantee high operating safety
• Metal housing ensures high stability
• Xenon flash lamp source with extremely long service life (10 years)
• Ready to measure immediately (no warmup time)
• Self-explanatory, extremely simple operation
• Measurement only takes approx 2 seconds
• Programmed methods: ssDNA, dsDNA, RNA, Oligo, Protein, Lowry/Lowry micro, Bradford/Bradford micro, BCA/BCA micro, and OD 600
• Optional background correction at 320 nm for UV methods
• Automatic calculation of sample dilution
• Simple conversion using the "Conversion" key
• Up to 10 standards for colorimetric analyses
• Storage of the last 100 results and all corresponding data
• Storage of all calibrations
• Sample data and calibration data can be called up after being stored

The Eppendorf BioPhotometer minimizes the workload for everyday routines in
molecular biology and biochemistry. The easy-to-follow keypad speeds operation.

Each method has its own key and parameters are set automatically when the method
is selected. Programmed methods include ssDNA, dsDNA, RNA, Oligos, Protein OD
600; and Lowery, Bradford, BCA (plus micromethods).
